Revisão taxonômica de Acianthera sect. Pleurobotryae (Orchidaceae, Pleurothallidinae)
Acianthera Scheidew. envolve cerca de 200 espécies de distribuição Neotropical; na mais recente sinopse taxonômica proposta para o gênero, Chiron & van den Berg criaram dez seções, dentre elas a Acianthera sect. Pleurobotryae, objeto deste estudo.

Molecular characterization and phylogenetic relationships among and within species of Phalaenopsis (Epidendroideae: Orchidaceae) based on RAPD analysis [PDF]
Random amplified polymorphic DNA (RAPD) analysis for 20 species of Phalaenopsis was conducted to determine their genetic distances and relationships. Among 20 different primers used for RAPD analysis, 10 primers showed polymorphism, and according to the ...

Fossil biogeography: a new model to infer dispersal, extinction and sampling from palaeontological data. [PDF]
Methods in historical biogeography have revolutionized our ability to infer the evolution of ancestral geographical ranges from phylogenies of extant taxa, the rates of dispersals, and biotic connectivity among areas.

ABSTRACT Aim The historical origins of biota in the Sunda Shelf region of Southeast Asia represent a long‐standing contentious issue in evolutionary biology. However, there is still no general agreement on the key factors driving the region's high species diversity and endemism in both plants and animals. Here, we inferred the evolutionary history of a

The curious case of the camelthorn: competition, coexistence and nest-site limitation in a multispecies mutualism [PDF]
Myrmecophyte plants house ants in domatia in exchange for protection from herbivores. Ant-myrmecophyte mutualisms exhibit two general patterns due to competition between ants for plant occupancy: i) domatia nest-sites are a limiting resource and ii) each

SUMMARY Rapidly radiated groups are usually accompanied by unclear lineage and taxa delineation, which complicates their better understanding in terms of biodiversity, evolutionary processes, and taxonomic treatment. The most species‐rich orchid subtribe, Pleurothallidinae, exemplifies an extremely diverse group with a complex evolutionary history ...

Standard DNA barcodes often fail to distinguish closely related plant species due to deep coalescence, hybridization, and low‐sequence variation. In this study, we demonstrate that single‐copy orthologs (SCOs), widely used in metazoan taxonomy, can serve as effective multilocus markers for plant species identification.

Leave it to the leaves: a molecular phylogenetic study of Malaxideae (Epidendroideae, Orchidaceae) [PDF]
Nuclear ITS and plastid matK sequences were collected for 71 taxa of Malaxideae (Orchidaceae). Resulting cladograms are highly resolved and well supported by jackknife analyses. These indicate that the traditional classification system of the tribe using characters primarily related to floral morphology does not reflect the evolutionary history of ...
